Indeed, Baumgart et al. found that VIM expression was mainly detected in invasive BlCa (31% in MIBC vs. 7% in NMIBC) and positively associated with tumor grade and stage, whereas Paliwal et al. found that VIM immunoexpression correlates with BlCa stage and grade 37, 38. This evidence concerns the gene VIM and bladder transitional cell carcinoma.
